Saving NSString with writeToFile will only save to one location - objective-c

Question

Using the code below is the only way I can get writeToFile to actually save a file. It outputs to this directory:
/Users/Eric/Library/Containers/net.ericmann.Event-Gadget-Workshop-App/Data/Documents/gadget.ics
- (IBAction)Saved:(id)sender {
[self writeToTextFile];
//mySaved.stringValue = [NSString stringWithFormat:#"Saved!"];
}
-(void) writeToTextFile{
//get the documents directory:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
//NSString *pathToDesktop = [NSString stringWithFormat:#"/Users/%#/Desktop", NSUserName()];
//make a file name to write the data to using the documents directory:
NSString *fileName = [NSString stringWithFormat:#"%#/gadget.ics", documentsDirectory];
//create content - four lines of text
NSString *content = myOutput.stringValue;
//save content to the documents directory
[content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];
mySaved.stringValue = fileName;
myTestBox.stringValue = fileName;
}
Now, if I use the code below, nothing will write. I have the test file name output, and it's pointing here:
/Users/Eric/Desktop/gadget.ics
-(void) writeToTextFile{
//get the documents directory:
// NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
//NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pathToDesktop = [NSString stringWithFormat:#"/Users/%#/Desktop", NSUserName()];
//make a file name to write the data to using the documents directory:
NSString *fileName = [NSString stringWithFormat:#"%#/gadget.ics", pathToDesktop];
//create content - four lines of text
NSString *content = myOutput.stringValue;
//save content to the documents directory
[content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];
mySaved.stringValue = fileName;
myTestBox.stringValue = fileName;

You will likely end up figuring out a solution if you actually make use of the error parameter there in the "writeToFile" method:
e.g.:
NSError * error = NULL;
BOOL success = [content writeToFile:fileName atomically:NO encoding:NSUTF8StringEncoding error:&error];
if(success == NO)
{
NSLog( #"error saving to %# - %#", fileName, [error localizedDescription] );
}
